- the several parts of a multipart receptacle closure.

A further object is to provide a simple and efficient mechanism for simultaneously operating upon both ends of the body member of the receptacle, the operations at one end being for the purpose of strengthening and improving the appearance of that end, as by forming thereon a flange in the shape of what is known in the art as a wire edge, and adapting said end to receive a friction closure, and the operations at the other end being for the purpose of attaching a head part to said other end, and to arrange said mechanism to operate in such manner that the performance of the operations at each end will assist the performance of the operations at the other end.

A further object is to provide means whereby. the parts of the receptacle will be assembled with no raw edges exposed interiorly or exteriorly thereof.

A further object is to provide means for forming a very efiicient, usually air tight, seam between the body member and head part. i

A further object is to provide a machine in which the die and immediately associated parts may be altered at will for forming receptacles of different shapes and proportions, either cylindrical, oblong, or otherwise.

A further object is to provide a machine as above, in which the several steps of the formation of a receptacle are simultaneously performed at different parts of the machine, so that a completed receptacle is discharged from the machine coincident with the performance of each and every step in the operationof the machine.

A further object is to render the operations at the opposite ends of the receptacle sharp and quick, and to provide means whereby the intermediate portion of the receptacle may be held securely against collapse under the pressures brought to bear thereon incident to the operations at the opposite ends of the receptacle.

A more detailed object is to provide a rotatable die plate having a number of dies or horns spaced apart thereon, to provide means for feeding hollow body members on to said horns, to provide means for feeding head parts to the body members upon said horns, to provide means for simultaneously forming a flange at one end of each of said body members and for locking the head parts to said body. members, to provide means for improving the lock between the body members and the head parts, to provide means for rotating the die plate step by step to dispose the horns in position for cooperating with other mechanisms to suecessively perform the above functions, to provide means for locking the die plate relatively to the parts of the mechanism cooperating therewith to perform said functions, and to provide means for discharging the "completed receptacles from the horns.

A further object is to design and arrange the parts of the above mechanism so that they may be employed as an attachment, if desired, to a machine now known in the art fpr forming hollow body parts of receptac es.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious, and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and

the scope of protection contemplated will be Fig. 3 represents an end view of the strucv ture shown in Fig. 1, said view being taken from the right-hand end of Fig. 1.

Fig, 9 represents an enlarged central sectional view through a receptacle constructed in accordance'with this invention; and

Figs. 10 and 11 represent slight modifications thereof.

As above stated, it will be understood that the principles of this invention may be employed for the manufacture of receptacles of various shapes, either cylindrical, oblong, square, elliptical, or otherwise; For convenience of illustration, however, the receptacles here shown are cylindrical.

The hollow receptacle body members or cylinders may be formed in any desired manner, either seamless or otherwise, and they may be fed to the devices comprised in this invention in any approved manner. The manner indicated in the drawing, Fig. 1 is merely illustrative and consists of a mandrel L about which the cylinders are formed in a manner, suggested for instance in my co-pending application, Serial Number 787,311. A series of fingers 1 reciprocating longitudinally of the mandrel L moves the cylinders or bodies 2 step by step along the mandrel toward the righthand end thereof.

A rotatable die plate G is arranged adjacent the right-hand end of the mandrel and carries a series, preferably 5 in number, of horns or dies 3 spaced apartat even distances thereon. One of these horns stands in position to receive the body members 2 directly from the mandrel L. The others stand in positions to codperate with other devices to be hereinafter specificall describe The die plate G is carried by a shaft l rctatably mounted in the main frame H of the machine. A ratchet 5 is also fixed to said shaft and a reciprocating pawl 6, driven by a link 7 from a rotating shaft 8, is arranged to engage said ratchet and rotate the shaft 4: and die plate G one step with each rotation of said shaft 8.

The shaft 8 is driven from the main power shaft 9 by means of the gears 10 and rotates at the same speed as saidpower shaft.

The ratchet 5 is providedwith one tooth for each of the horns 3, and is advanced the space of one tooth with each revolution of the shaft 8.

The horns 3 are of a shape and size to fit fairly closely to the interior cross sectional contour of the receptacle body members. They are however, somewhat shorter than the full length of the body members, the approximate proportions being best seen in Fig. 1.

* After a body member has been telescoped over one of the horns the die plate G is ad- I vanced a step to cause said horn to register with the mechanism for inserting the head part within the body member.

This mechanism comprises a rod 11 slidably mounted in suitable bearings 12 carried upon the main frame H. A collar 13 is fitted to said rod and a compression spring 14 engages between said collar and one of the bearings 12 to yieldingly retain the rod pressed backwardly toward the left in Fig. 1. The collar 13 may engage the other bearing 12 to limit this backward movement. ,The right-hand or outer end of the rod 11 is formed with an enlargement 15, which is arranged to slide back and forth through an aperture 16 extending transversely through the lower or discharge end of a feed chute 17 for the head parts of the receptacles.

A guard plate 18 is carried by the die plate Gr, being supported by brackets 19 extending from said die plate. This guard plate preferably has rubbing engagement with the outer surface of the feed chute so as to close the outer side of the aperture 16 at all time except when one of the horns 3 coincides with said aperture.

The shape of the guard plate 18 is best shown in Fig. 1, wherein it will be seen that openings 20 are formed therein adjacent each of the horns 3 and that the intermediate portions of said plate between said openings 20 lie in the circumferential path of the discharge end of the chute 17.

The enlargement 15, at the inner side or end of the aperture 16 and the guard plate 18 at the outer side or end of said aperture define a pocket 21, within whichflthelower most head part 22 in the chute-17 will rest until one of the openings 20 and the adjacent horn 3 with its body member 2 is mes es moved to register therewith, whereupon the enlargement 15 will move throughthe aperture 16 and through the opemng 20 into ing head part.

The enlargement 15 may be shaped to pressthe head part home within the body member if desired, but preferably a separately movable plunger 24 is carried thereby and is connected with a plunger rod 25 slidable longitudinally within the rod 11. The plunger rod is slightly longer than the rod 11, and a compression spring 26 is arranged for retaining the outer surface of the plunger 24 flush with the outer surface of the enlargement 15 and for thereby retaining the inner end of the plunger rod proj ected beyond the inner end of the rod 11.

A slide plate 27 is carried by the main frame H, and is arranged to be reciprocated by means of a cam 28. This cam is mounted upon the power shaft 9, and engages friction rollers 29 and 30, carried by the slide plate. An arm 31 extends from said slide plate to a position for engaging the inner end of the plunger rod 25 upon each reciprocation of the slide plate. An adjusting screw 32 may be carried at the end of the arm 31 for determining the extent of movement to be imparted from the arm 31 to the plunger rod 25 and rod 11, as will be readily understood.

As the arm 31 moves forward the plunger 24 will first be projected out of the enlargement 15 and into engagement with the inner surface of the head part 22 within the pocket 21. The plunger 24 and the enlargement 15 will then move together through the adjacent opening 20 and into the adjacent body member 2, the plunger 24 pressing the head part home within the body member. As the arm 31 withdraws the plunger 24 will-recede into the enlargement 15 and the two will return to their normal positions.

The diameter of the head part is such as to cause the head part to fit snugly within the body member and be retained by friction against aecidental displacement during the subsequent movement of the horn.

After the head part has been inserted within the body member the die plate G is advanced another step to cause the horn upon which the two parts are carried to;

register with the mechanism for locking said parts together.

This mechanism comprises'a die 33 connected to move with the slide plate 27. A separate guide as 34 may be provided for the die 33 if desired;

This die is provided with an annular recess 35, in its outer end, said recess being of a size to fit snugly over the end of the body member 2. The inner wall of the recess is formed with an annular groove 36, as best seen in the enlarged view in Fig. 8.

As the die telescopes over the body member 2, the inner annular edge of said body member engages the curving walls of the groove 36, and said annular edge is caused to curl inwardly upon itself, to form a flange in the manner illustrated in Fig. 7.

It will be here noted that the head parts each consist of a disk ortion and an annular laterally extending ange upon said disk portion. This-head part is inserted within the body member with its flange projecting away from the horn upon which the body is being carried. Also each head part is inserted within the body member to a distance so that a portion of the body member projects beyond the flange, as clearly shown in Fig. 1'. It follows therefore that, as the projecting portion of the body member engages the groove 36 and is curled or flanged over, the curling action is also imparted to the flange of the head part and this too is curled upon itself and between the curled and lapping portions of the body member so that the parts become inseparably and immovably locked together. r

The horns 3 and the dies 33 may be provided with any suitable cooperative forma tions, as indicated at 37, for changing the shape of the disk portion of the head part. The parts 37 illustrated are designed to effect the shape shown in the drawings, especially in Fig. 9 thereof, but obviously any other appropriate shape may be obtained in the same manner.

In order to insure the head part being held in its proper relative position within the body member the die 33 preferably carries a yielding plunger 38. This plunger is spring pressed outwardly beyond the inner wall of the recess 35 and is designed to engage the inner surface of the head part and press said head-part firmly against the horn 3. As the die advances to its work the plunger 38 recedes relatively with respect to the die, against the pressure of the spring 39.

In order to adjust the die 33 relatively to the slide plate 27 so as to bring the operating parts thereof into precise position relatively to the horns upon the die plate, said die 33 is formed with annular threads 40 thereon and a sleeve 41 engages said threads, said sleeve also having threads engaging a threaded portion 42 of the slide plate 27 The threads engaging between the sleeve and the die 33, and the threads engaging between the sleeve and the part 42 are cut in reverse directions so that rotation of the sleeve will move the die 38 toward or away from the part 42 according to the direction of rotation of the sleeve. A series of sockets or other means as 43 may be provided upon the sleeve for rotating the same, and a lock nut 44 may be provided either upon the die or upon the part 42 for locking the sleeve in any position.

After the head part and the body member have been locked together as above described, the die plate is advanced another step to cause the horn upon which the two parts are carried to register with mechanism'for operating upon the locking formations of the parts of the receptacle to press said locking formations into tighter engagement.

This mechanism is usually not necessary for the reason that the adjustments above described for effecting the locking operation are such as to render the initial locking operation all that is necessary in most cases.

In Fig. 2 of the drawings, however, there is illustrated by dotted lines at 45 a mechanism substantially a duplicate of the locking mechanism above described. The mechanism shown at 45 may be adjusted to afford a closer engagement between the die thereof and the horn upon which the receptacle is being carried.

In case this mechanism at 45 for further operating upon the'locking parts of the receptacle is omitted, the parts of the receptacle will stand without being operated upon for a short period while the heretofore mentioned operations are being performed upon other succeeding receptacle parts.

After the additional locking operation has been performed, or after the required lapse of time for such operation, the die plate is advanced another step to cause the horn upon which the receptacle is carried .to register with mechanism for discharging the completed receptacle from the horn.

This mechanism comprises a bell-crank lever 46 pivotally mounted upon the main frame H and having one of its ends provided with an anti-friction roller 47 engaging within a cam slot 48 of a sleeve 49 carried by and rotatable with the shaft 8. The opposite end 50, of the lever 46 is arranged to engage the outer end of a discharge plunger 51, one such plunger being slidably mounted within each of the horns 3 and being yieldingly pressed outwardly by means of a compression spring 52.

The arm 46 will move the discharge plunger to force the completed receptacle 0d of the horn. I

It will, of course be understood that a new body member is fed to one of the horns 3 at each step in the movement of the die plate G, and that the operations above described also take place at each step in the tacle parts.

movement of said die plate, the successive operations of'each mechanism being performed upon successively advancing recep- It is apparenttherefore, that with each step in the movements of the die plate a completed receptacle will be discharged by the discharge plungers 51, and that the respective horns from which the completed receptacles are discharged will move, at the next step of the die plate, to a position to receive a new body member from the mandrel L.

In order to, insure that the die plate shall stand in precisely the proper position for disposing the various horns thereof in 00- operative relation with the other mechanisms, a locking pin 53 is connected to move with the slide plate 27, being preferably mounted for convenience upon the die 33. The die plate is formed with a series of-apertures 54 arranged to receive the locking pin as the same moves forward, following 7 each advancing step of the die plate.

The locking pin is preferably tapered at its outer end so as to insure engagement with one of the apertures 54 and any suitable means may be provided for afiording a slight movement of the die plate to accommodate the die plate to the. locking pin in case the ratchet and pawl mechanism 5 and 6 is not precisely accurate. As an example of such means the die plate may be mounted,

loosely upon the shaft 4 and a spring pressed friction-clamp member 55 be arranged to engage between'the shaft of the die plate.

In order to increase the rapidity with which the parts of the mechanism above set forth may operate, it is desired that the op erative movements thereof, especially of the die 33, shall be for as short distance as possible. For small receptacles, such as pill boxes, bottle caps, and the like, a recess 35 in said die may be of a depth to telescope the entire exterior circumferential surfaces of the body member, and thereby prevent buckling of the body member under the pres sure employed to lock the body member with the head part, for in these instances the entire movement required of the die would be not more than one half an inch, to an inch. In the manufacture of larger receptacles however, it is desirable that the recess 35 be shallow so as to inclose only a portion of the length of the body member, as for instance as seen in Fig. 7 The short, half inch to an inch, movement may be thus maintained.

Where the recess is shallow a separately I ranged at each side of the horn, and being connected by a common pivot pin 57 to the die plate G. The free ends of the jaws are provided with cross slots 58, and a ever 59, also pivotally carried by the die plate as by a pivot pin 60, is provided with a pin 61 engaging within said cross slots to-move the jaws toward and awa from the horn according to the position 0 the pin 61 within the cross slots. A spring 62 is arranged for retaining the pin 61 in position to hold the jaws open, and an ant1-friction roller 63 is arranged for engaging a stationary cam 64 for moving the pin 61 to close the jaws tightly against the horn, or rather against the exterior walls of the body member carried by the horn.

Since it is necessary that the jaws be closed only during the operation of the means for locking the parts of the recep- 'tacle together, the cam 64 is preferably arranged in such position only as to be engaged by the anti-friction roller 63 during the time when the locking devices are operating. The cam 6% is adjustable as by means of the slots 65 so as to modify the precise position at which the same becomes effective.

The anti-friction roller 63 is preferably carried upon a stiff plate spring member 66 so that slight inaccuracy may occur Without detrimental effect upon the grip of the jaws I 56, as will be readily understood.

In the interests of clearness of the drawing only one of the braces is illustrated in Fig. 4:, but it is apparent that there will be one such brace at each of the horns. The small dotted circles 67 in this figure indicate the relative positions of the roller 63 of the braces of the respective adjacent horns, and show that the braces of the two lowermost horns are held closed by engagement of their anti-friction rollers with the cam 64. The position of these lowermost horns coincides with the positions of the locking devices.

In some instances it may be desired to perform no other operation upon the parts of the receptacle than to lock the parts thereof together, but as above set forth it is a feature of this invention to provide means not only for locking the parts together, but for improving the appearance of and strengthening the opposite or outer end thereof.

One means for improving the appearance of and strengthening the outer end of the receptacle is byforming a flange thereon, in the shape of a wire edge, and to this end the mechanism above described is adapted to produce a wire edge simultaneously with the locking together of the parts of the receptacle.

Each of the horns 3 is formed with an annular shoulder 68 at its base with which the outer end of the body member engages for resisting the pressure of the die 33. In

of the receptacle.

order to curl or'flange back the material of the body member to form the wire edge, the 1 shoulder 68 is provided with an annular groove 69 and the pressure of the outer end of the body member against the curving Walls of this groove will induce the material of said end to follow said curving walls and be flanged or folded back upon itself. in somewhat the same manner as above described for the groove 36 in the die 33.

The formation of the flange or ,wire edge, coincident With the flanging and looking together of the parts of the receptacle has many advantages, namely among which may be stated: 1The same power and time required for forming the flange or wire edge at one end is simultaneously utilized for forming the flange and locking means at the other end. 2-The wire edge provides a relatively broad and substantial surface engaging the shoulder 68 to resist the pressure from the locking die and render the looking die more effective Without danger of buckling the material of the body member 3The gradual creeping of the body member longitudinally along the horn as the wire edge is formed assists in overcoming the tendency of the body looking die. 4-The formation of the looking parts provides a positive and substantial abutment for receiving the pressure to move the body member longitudinally for forming the wire edge. 5The-gradual movement of the body member relatively to the head part during the formation of the locking parts materially improves the quality of the lock obtained.

These advantages of simultaneous operation at the opposite ends of the receptacle go far toward the production of uniformly eflicient and uniformly attractive receptacles.

As the die moves toward the horn the similarly curved surfaces of the grooves 36 and 69 will cause the opposite ends of the body member to curve or flange simultaneously, the inner end fianging inwardly, and the outer end flanging outwardly. The body member moves bodily with respect to the head part, even after the formation of the locking part at its inner end begins. As the inner end curls over in the groove 36 the body member slides bodily outwardly over the flange of the head part, and the curved walls of the body member being formed by the groove 36 to engage the flange of the head part, and while still attempting to slide outwardly over the flange of the head part, cause said flange to curl. The result is a very tight look. A small quantity of sealing material placed upon the parts of the receptacle, as for instance lacquer,

' or the like, serves to render this joint praction of the wire edge, and the steps in the formation of the locking parts coiiperate and beneficially afiect each other in such manner that the wire edge is uniform throughout its extent, and the locking parts are likewise uniform throughout.

It will be noted that the dies 33 are readily detachable by rotation of the sleeve 41. Dies of difierent shapes and proportions may be attached at will. The horns 3 are also detachable, as by means of the clamp screws 70, for the same purpose. Diderently shaped receptacles may thus be formed by merely changing the die and horns.

In the structure shown in Figs. 10 and 11, the body member of the receptacle is shown to be provided with annular corrugations 71 either inthe form ofthreads, or otherwise, and to be provided also with short vertical corrugations 72, to serve as a finger ip. The corrugations 71 stifien and preserve the shape of the receptacles.

Here, it may be noted that the open end of the receptacle, about which the wire edge is formed, is adapted to be closed by a separately formed closure member. Usually a closure member commonly known as a friction closure is employed and this may have its marginal flange engaging the inner wall surface of thereceptacle or the outer wall surface thereof, as will be readily appreciated by those familiar with the art. In either instance the wire edge will efliciently strengthen the end of the receptacle and assist in the retention of the closure member. It, and the corrugations 71, will also give added body and form to the end of the receptacle and serve to maintain the same in normal shape to receive the closure member.

It is to be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of myinvention, and hence I do not intend to be limited to the details herein shown and described except as they may be specifically included in the claims.
